Prospective follow-up of the Prevision hip stem with comparison of implant variants

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational post‑market follow-up of patients treated with the Prevision revision hip stem, designed as a non‑inferiority comparison of two‑year functional outcomes measured by the Oxford Hip Score (OHS) against the predecessor implant generation and comparable revision stems. Study sites choose which Prevision variant to implant according to routine practice, with all variants available and switching between variants encouraged. The primary focus is patient‑reported function at two years, with descriptive comparisons of subgroups treated with different stem variants and systematic collection of clinical performance and safety data. No randomized assignment is used; outcomes reflect real‑world use across participating orthopedic centers.
